503.06(b)
Typographical Errors in Recorded Assignment Document

If there is a typographical error in the recorded assignment
document (or other document affecting title) rather than in the cover sheet, the party
responsible for the erroneous document (e.g., the assignor) must either record a new
document with the Assignment Recordation Branch or make corrections to the original
document and re-record it. If the assignor is not available to correct an original
document or execute a new one, the assignee may submit an affidavit or declaration for
recordation in which the assignee identifies the error and requests correction. The
affidavit or declaration must: (1) be signed by someone with firsthand knowledge of the
facts and (2) identify the current owner of the property and explain why the originally
recorded document was erroneous. To record the affidavit or declaration, the assignee must
file: (1) a new complete cover sheet; (2) the affidavit or declaration; (3) a copy of the
originally recorded document with the corrections thereto initialed and dated by the party
signing the affidavit or declaration; and (4) the required fee for each application or
registration to be corrected (37 C.F.R. §§2.6 and 3.41). See In re Abacab Int’l
Computers Ltd., 21 USPQ2d 1078 (Comm’r Pats. 1987). See TMEP §503.03(e) for information about the
cover sheet.

In an application under §66(a) of the Trademark Act or a
registered extension of protection, any request to correct an error in a document recorded
with the IB must be corrected at the IB. Such a request cannot be sent to the IB through
the USPTO.
